WILLIAM F. WEST, OF SLATERSVILLE, RHODE ISLAND.

FRICTION-COLLAR FOR SPINDLES ON LONG-CHAIN QUILLING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 478,269, dated July 5, 1892.

Application filed March 14, 1892. Serial No. 424,857- (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM F. WEST, a citizen of the United States, residing at Slatersville, in the county of Providence and State of Rhode Island,- have inventedv certain new and useful Improvements in Friction-Collars for Spindles on Long-Chain Quilling-Frames; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a friction-collar especially designed for use in filling bobbins with yarn on long-chain quilting-machines; and the object is to more effectually prevent the yarn from pulling ofi from the end of friction-collar onto the spindle during the interval when one bobbin is dofied and another is placed on the spindle, and to provide for the ready removal of the accumulated yarn on the collar without liability of destroying and dulling the edge of the implement used to cut the yarn in order to facilitate its removal.

With these ends in view the invention consists of a friction-collar provided with an enlarged or flanged upper end forming a socket to receive the lower extremity of the bobbin and having a vertical groove or recess formed in one of its faces and extending into the enlarged or flanged upper end of the collar and into the base of the same, as will be more fully hereinafter described.

In the accompanying drawings, Figure l is a view illustrating an elevation of a bobbin, a part of a rail, the spindle-whirl, and my improved friction-collar, the outlines of the spindle and the yarn adapted to be wound on the bobbin being indicated by dotted lines. Fig. 2 is an elevation of the collar detached from the spindle and other parts. Fig. 3 is a sectional View through the collar-shown in Fig. 2 with yarn wound thereon and illustrating the method of removing the yarn without impairing the knife-edge. Fig. 4: is a detail view of another embodiment of my 7 improved friction-collar.

Like letters of reference denote corresponding parts in all the figures of the drawings.

Referring more particularly to Fig. 1, Aindicates a part of the rail or frame of the wellknown form of quilling-machine, and from the under side of the rail depends the bolster B, which is rigidly attached to the rail and serves to support thelower end of the spindle O. (Indicated by dotted lines in Fig. 1.) Above the rail and rigid with the spindle is the whirl D, adapted to be driven by a belt from a drum (not shown) in the usual manner, and between the vertical bobbin E and the whirl D is interposed a friction-collar F. This collar is shown in detail in Figs. 2, 3, and 4, and it is made of a-single piece of metal with a central longitudinal passage f, in which the spindle O is loosely fitted. The spindle is adapted to be rotated positively by the whirl which is rigid therewith; but the rotation of the collar F and the bobbin E, supported thereby, depends upon the degree of friction between the Whirl, the collar, and a soft pad or cushion G, which is interposed between the whirl and the collar. The pad or cushion'is composed of felt or other suitable material, and its periphery or edge lies flush with or within the edges of the whirl and the collar.

The friction-collar F is enlarged or flared at its base, as at g, and the upper end of the collar is enlarged by forming a flange h there on, as in Fig. 4, or by extending the flared upper part vertically into the vertical mouth t' in Figs. 2 and 3.

In the practical operation of winding yarn on the bobbin it is carried down by the wavemotion guide or rod J below the base of the bobbin and is coiled a few times around the friction collar to preserve the continuous thread when the bobbin is doffed and another bobbin is placed over the spindle, after which the guide J is raised to the base of the bobbin and the operation of filling is repeated as is customary. Difliculty has heretofore been experienced While dotting the bobbin in preventing the yarn from being drawn over the upper end of the collar upon the spindle, thereby impeding the proper seating of the bobbin and in removing the accumulated yarn from the friction-collar. These objections I aim to overcome by the collar constructed as herein specified. The lower end of the bobbin when it is placed on the spindle fits loosely in the socket formed by the enlarged extended end i of the collar or the flange h, and the diameter of said upper end bore or of the collar is such that the yarn when the wave-motion guide J is lowered cannot be come coiled around the spindle above the collar, but the yarn must coil around the collar between its enlarged upper end and the flared base thereof, as indicated in Fig. 3.

To provide for the ready removal of the accumulated yarn on the collar, I provide a longitudinal groove or recess j, which is formed in the outer face of the collar, and the upper end of this groove or recess opens into or through the enlarged upper end i of the collar and extends into the base, whereby the point of a knife or implement K (indicated at Fig. 3) can be inserted into said groove or recess and forced down through the accumulated yarn to cut the same and permit its expeditious removal without dulling the knife or implement.

As usual, the collar is provided with a central tubular stud Z, which is adapted to fit into the lower flared end of thebobbin, and through which the spindle passes, and the collar and bobbin are coupled or connected by means of a lug or pin on, which is rigid with the collar in the socket thereof and takes into an aperture in the lower end of the bobbin.

In operation the spindle G is rotated independently of the bobbin by its whirl, and the connected collar and bobbin are rotated by the friction between the pad and the whirl upon which rests the collar F, which keeps the proper tension upon the yarn while being wound upon the bobbin. After the bobbin has been filled and is ready for dotting, the wave-motion guide or rod J is at the top of the bobbin, and the operator brings the guide below the bobbin, so that the yarn is wound upon the friction-collar, while the filled bobbin is removed and anotherbobbin placed on the spindle, so that a continuous strand of yarn is retained ready for repeating the operation upon the unfilled bobbin, the guide J being raised to convey the yarn to the heel or flared end of the new bobbin ready for commencing the operation. In the course of time the collar will become filled with yarn, which accumulates thereon while the bobbins are dotted, and to remove this yarn from the collar it is only necessary for the operator to insert the point of a knife in the groove and draw the knife through the yarn on the collar, thus insuring the easy and expeditious removal of the yarn from the collar.

Having described my invention, what I claim as new is-' 1. A friction-collar for quilling-machines, provided with the longitudinal recess or groove in its exposed face, substantially as and for the purpose described.

2. Afriction-collar for quilling-machines, having the flared base and the enlarged flanged upper part forming the socket, and the longitudinal recess or groove in the outer face of said collar, which is extended into the flared and flanged ends of the collar, substantially as and for the purpose described.

3. The combination, with a spindle, the whirl thereof, and a bobbin, of the frictioncollar having the enlarged upper end provided with a socket receiving the lower end of the bobbin and the pin or stud which connects said bobbin and the collar, and ayielding pad interposed between the collar and the whirl, substantially as and for the purpose described.

In testimony whereof Iaffix my signature in presence of two witnesses.
